    i see this video of a kid who makes a plane from an equilateral triangle .. it looks SO cool ... so i decide "I'll build one too". A couple of hours later, i'm in the front yard ... radio, battery, full throttle, toss into the air at somewhere between 30 and 45 degrees, and ...

    ... two seconds later it's nose down in the dirt with a broken propeller. I figure i've just got the center of gravity too far forward.

    so, here's my question ... WHERE is the center of gravity on a perfect equilateral triangle??

    The f117 v2 was way up towards the nose, about 3 inches back from the nose. CG was still forward of the center point. I was able to push it way back and got good flight. That was the first plane I started pushing back the cg.

    20-30% back from the front of the triangle usually works...
